ABSTRACT

In this paper, we present the new techniques to analyze how to design a lightwave communications link. Specially, we introduce a direct detection, single mode fiber link utilizing a light emitting diode source, and either a pin photodiode or avalanche photodiode receiver, We discuss about a point to point link, even though an optical fiber communications link is usually part of a larger communications network. The optical fiber link has enormous bandwidth. Wavelength division multiplexing is one way of utilizing this bandwidth. Ideally, the purpose is to find a set of parameter values for the various subsystems in the link that will satisfy certain performance objectives. There can be a large number of parameters, each having a range of valid values. Processing power of computers is increasing at a rapid rate, and one way to take advantage of this increased power is to let the computer handle the details of searching for the optimal set of parameter values. The research for an acceptable design is based on multiple simulations, and is a trial and error search if done manually. we give a general method of the modeling approach, the key blocks and parameters of a lightwave communications link.
